NVIDIA is showing no mercy in the battle for graphics card supremacy. It has been less than a month since they dropped the GeForce 660 Ti on the masses, yet here we are again as the relentless assault continues with the launch of the GTX 660. You may want to think twice before you begin to compare the GTX 660 against the GTX 660 TI, 670 or even 680 cards, because the GTX 660 is built around the new Kepler GK106 GPU.
The new GK106 retains all of the ground breaking innovations NVIDIA introduced with the release of the GTX 680 including the 28nm fabrication process as well as two major performance increasing features: the Streaming Multiprocessors (SMX) architecture and the incredible GPU Boost technology. The GTX 660 has been trimmed down in a few areas. The number of CUDA cores has been reduced to 960, while the number of Graphics Processing Clusters (GPCs) has dropped to three, one less the GTX 660 Ti.

waiting thought for the next gen with hopefully beefier bus width.
